- Security_protocol_notation abstract "In cryptography, security (engineering) protocol notation is a way of expressing a protocol of correspondence between entities of a dynamic system, such as a computer network. In the context of a formal model, it allows reasoning about the properties of such a system.The standard notation consists of a set of principals (traditionally named Alice, Bob, Charlie, and so on) who wish to communicate. They may have access to a server S, shared keys K, timestamps T, and can generate nonces N for authentication purposes.A simple example might be the following:This states that Alice intends a message for Bob consisting of a plaintext encrypted under shared key KAB.Another example might be the following:This states that Bob intends a message for Alice consisting of a nonce encrypted using public key of Alice.A key with two subscripts is a symmetric key shared by the two corresponding individuals. A key with one subscript is the public key of the corresponding individual. A private key is represented as the inverse of the public key.The notation specifies only the operation and not its semantics — for instance, private key encryption and signature are represented identically.We can express more complicated protocols in such a fashion. See Kerberos as an example. Some sources refer to this notation as Kerberos Notation. Some authors consider the notation used by Steiner, Neuman, & Schiller as a notable reference.Several models exist to reason about security protocols in this way, one of which is BAN logic.".
